# CONSTRAINTSETTINGS Command [GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [Commands](Help%20System/GSTARCAD/2027/Commands/(Commands).md) → [C](Help%20System/GSTARCAD/2027/Commands/C/(C).md) ## Function Description: Controls the display of geometric constraints within the CAD software. ## Command Access: Icon:  Menu Item: Parametric (P) > Constraint Settings (S) Ribbon: Parametric > Constraint Settings Toolbar：/ Command Line: CONSTRAINTSETTINGS Command Alias ：/ ## Command Prompts: ``` Constraint Settings: Opens the Constraint Settings dialog box. ``` ## Operation Steps: 1、Open the Constraint Settings dialog box as shown   ## Geometric Tab (Constraint Settings Dialog Box) Controls the display of geometric constraint types on constraint bars. ### Infer Geometric Constraints Infers geometric constraints when creating and editing geometry. ### Constraint Bar Display Settings Controls the display of constraint bars or constraint point markers for objects in the drawing editor. ### Select All Selects the geometric constraint types. ### Clear All Clears the selected geometric constraint types. ### Only Display Constraint Bars for Object in the Current Plane Displays constraint bars for geometrically constrained objects only on the current plane. ### Constraint Bar Transparency Sets the transparency level of constraint bars in a drawing. ### Show Constraint Bars After Applying Constraints to Selected Objects Displays relevant constraint bars after you apply a constraint manually. ### Temporarily Display Constraint Bars When Objects Are Selected Temporarily displays the constraint bars of the selected objects. ## Dimensional Tab (Constraint Settings Dialog Box) Controls dimensional constraint settings on the constraint bars. ### Dimensional Constraint Format Sets the display of the dimensional name format and lock icon. ### Dimension Name Format Specifies the format for the text displayed when dimensional constraints are applied. ### Show Lock Icon for Annotational Constraints Displays a lock icon against an object that has an annotational constraint applied (DIMCONSTRAINTICON system variable). ### Show Hidden Dynamic Constraints for Selected Objects Displays dynamic constraints that have been set to hide when selected. ## AutoConstrain Tab (Constraint Settings Dialog Box) Controls AutoConstrain settings on the constraint bar. ### AutoConstrain Headings - Priority — Controls the order in which constraints are applied. - Constraint Type — Controls the type of constraint applied to objects. - Apply — Controls the constraints that are applied when applying constraints to multiple objects. ### Move Up Changes the order of the selected item by moving it up in the list. ### Move Down Changes the order of the selected item by moving it down in the list. ### Select All Selects all geometric constraint types to autoconstrain. ### Clear All Clears all geometric constraint types to autoconstrain. ### Reset Resets AutoConstrain settings to default values. ### Tangent Objects Must Share an Intersection Point Specifies that two curves must share a common point (as specified within the distance tolerance) for the tangent constraint to be applied. ### Perpendicular Objects Must Share an Intersection Point Specifies that lines must intersect or the endpoint of one line must be coincident with the other line or endpoint of the line as specified within the distance tolerance. ### Tolerances Sets the acceptable tolerance values to determine whether a constraint can be applied. - Distance — Distance tolerance are applied to coincident, concentric, tangent, and collinear constraints. - Angle — Angular tolerance are applied to horizontal, vertical, parallel, perpendicular, tangent, and collinear constraints. --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/commandReferences_C/CONSTRAINTSETTINGS.html) · © Gstarsoft Co., Ltd.
